Well, I already admitted that.
Yes, I understand that. However, if I changed the angle of the cue that much at contact, the CB would not go in the direction I was aiming it - directly across and into the diamond on the other long rail.
I got enough spin to open the angle coming off the rail more than I could with my regular stroke. That's really all I was curious about.
BTW I am really envious of you. I see that your name is now first, in a very large font, and blue to boot. I'm at the tail end of the ENGLISH! hate list. I must not be trying hard enough.
